Inside Unit 731: Japan’s Secret Human Experiments
Inside Unit 731 is a gripping two-part investigation into one of Japan’s most secretive wartime programmes – a biological warfare unit that conducted lethal human experiments.
At the centre of this story is Hideo Shimizu, one of the unit’s last surviving members. Now in his late 90s, Shimizu breaks decades of silence to reveal what he witnessed as a teenage recruit inside the unit’s complex in Harbin, China.
Through survivor testimony, declassified documents and investigations across Japan, China, Singapore, the United Kingdom and the United States, the series uncovers how Unit 731 developed biological weapons, carried out human experiments and launched germ attacks on civilians. It also examines how post-war decisions, including a covert deal with the United States, helped bury the truth for decades.
More than eighty years later, Inside Unit 731 reveals one of the war’s most closely guarded secrets and asks why justice was never served.
